what term best describes the relationship of the bones in the forelimbs of penguins and seals, and what term best describes the flippers of penguins and seals?

Answers

Answer 1

(1) Homologous is the best describes the relationship of the bones in the forelimbs of penguins and seals.

(2) Analogous is the best describes the flippers of penguins and seals

Analogous organs have comparable functions, while homologous tissues share a similar embryonic origin. For instance, the bones in a human arm and a whale's front flipper are anatomically similar. The constructions here are not comparable. The wings of a butterfly and a bird are similar but not identical.

Analogous structures or analogous organs are any two structures or organs that have different structural characteristics but execute the same functions. Homologous organs are the opposite of similar organs. Organs that are structurally identical to one another but have diverse purposes are known as homologous organs.

The question is incomplete, it should be:

Both ancestral birds and ancestral mammals shared a common ancestor that was terrestrial. Today, penguins (which are birds) and seals (which are mammals) have forelimbs adapted for swimming. What term best describes the relationship of the bones in the forelimbs of penguins and seals, and what term best describes the flippers of penguins and seals?

Medicines called antifungals are used to treat infections caused by fungi. One way antifungals work is by targeting cell parts that are present in fungal cells but not in human cells.

c. Identify one cell part other than a ribosome or a plasma membrane that human cells and fungal cells have in common.

d. Describe what would happen to a human cell if the cell part you identified in part (c) were affected by an antifungal. Explain your answer based on the function of the cell part.

Answers

Answer:

see below

Explanation:

a. The parts of a cell called ribosomes are where proteins are created. They employ messenger RNA's genetic code to construct a chain of amino acids that will eventually fold into a particular protein. By interfering with the ribosomes, the bacteria would be unable to produce the proteins necessary for survival, which would result in their eventual death.

b.The plasma membrane is the cell's outermost layer of lipids and proteins. It serves as a barrier to restrict the flow of substances into and out of the cell. The capacity of the cell to maintain a healthy internal environment and interact with its surroundings would be disrupted by interference with the plasma membrane, which would ultimately result in the death of the bacterium.

c. Mitochondria are not a cell part that is present in both human cells and fungal cells. Fungal cells do not have mitochondria. Instead, they have other organelles called mitochondria-related organelles (MROs) that perform similar functions. I apologize for any confusion caused.

d. Through cellular respiration, mitochondria are organelles that create energy in the form of ATP. An antifungal would interfere with the cell's capacity to create energy and eventually kill it if it were to impact the mitochondria. Without energy, the human cell will perish since its metabolism won't function.

will work closely with legume. will be required to fix nitrogen in exchange for daily carbohydrate allowance

Answers

One anticipated advantage of utilizing legumes as a cover crop is to give the cropping system a supply of nitrogen (N).

However, the quantity of real fixed nitrogen may be minimal when legumes are mixed with grasses and broadleaves over a brief length of time. The quantity of fixed N may be less than expected, even when planted as a monoculture or a combination of solely legumes. Rhizobia bacteria in root nodules accelerate the chemical reaction known as "N fixing," which turns atmospheric N (N2) into ammonia (NH3). The energy generated by photosynthesis in the legume plant is used in this process.

Alleles randomly split during gamete formation, resulting in various combinations in daughter cells. In this case, the gametes are YS, Ys, yS, and ys.

How do gametes form?

Meiosis is the process through which gametes are created. Meiosis is a cell division process that results in the formation of gametes from germ cells. A diploid cell (2n) creates four haploid daughter cells via Meiosis (n). Alleles separate separately during gamete formation, according to the segregation principle. During anaphase I, homologous chromosomes split and travel to opposing poles of the cell, each carrying one of the alleles. This chance occurrence results in various chromosomal configurations in the daughter cells.

Let us now examine the issue.

what are the similarities and differences between the lactase persistence mutations found in african populations and the one found in european populations

Answers

Lactase persistence mutations observed in African and European populations are both point mutations that appear in distinct sites on the chromosome. Furthermore, the African gene employs a different method than the activator in the European gene.

Lactose persistence helps people to break down lactose in their bodies. Lactose persistence is caused by a mutation that occurs in African and European populations. The mutations share certain characteristics, including:

Lactose persistence is produced in both groups by single nucleotide polymorphism (SNP).

In both groups, the polymorphism does not appear in the LCT gene responsible for lactase production; rather, it occurs in the intron region of some other nearby gene that initiates the transcription of the LCT gene.

The following mutations differ in both populations:

Lactose persistence in the European population can be attributed to a single SNP in the intron region.

Answers

The mechanism of action of tetracycline antibiotics that can interfere with protein synthesis in bacteria prescribed for adult clients with chlamydia infection by prevents aminoacyl-tRNA from binding to the ribosomal acceptor (A) site, hence inhibiting protein synthesis.

Tetracyclines are broad-spectrum antibiotics that are effective against a variety of gram-positive and gram-negative bacteria, unusual microorganisms such chlamydiae, mycoplasmas, and rickettsiae, as well as protozoan parasites.

The 30S ribosomal subunit is selectively inhibited by tetracyclines, which prevents the aminoacyl-tRNA from attaching to the acceptor site on the mRNA-ribosome complex. A cell can no longer retain appropriate functioning and won't be able to expand or continue to duplicate if this process stops. Tetracyclines are referred to as "bacteriostatic" because of the way in which they impede.

Answers

The ATP molecule is just like a rechargeable battery. When it's fully charged, it's ATP. When it's run down, it's ADP.

However, the battery doesn't get thrown away when it's run down–it just gets charged up again. All biological organisms contain the crucial chemical ATP (adenosine triphosphate). Consider it the cell's "energy currency." The ATP molecule splits off one of its three phosphates when a cell has to expend energy to complete a task, resulting in the formation of ADP (Adenosine di-phosphate) + phosphate. That phosphate molecule's energy is no longer bound to it and can now be used by the cell to perform tasks. The cell stores extra energy by reattaching a free phosphate molecule to ADP, converting it back into ATP. This extra energy can come from the breakdown of food that has been ingested or, in the case of plants, energy produced during photosynthesis.

Think about a farm ecosystem. Draw and label the energy transformations that might occur on the farm. Remember, all energy should start from the sun and end up as heat somehow. Also, cow manure could be used as a biofuel inside the farm house. The picture should show at least three different energy conversions from the cow manure inside the home.

Answers

Answer:

I am not able to draw images, but I can describe the energy transformations that might occur in a farm ecosystem.

Solar energy: The sun is the primary source of energy for the farm ecosystem. The energy from the sun is used to power the growth of plants, which are then used to feed the animals on the farm.

Chemical energy: The energy stored in plants is converted into chemical energy through photosynthesis. This chemical energy is then used by the animals as they consume the plants.

Mechanical energy: The energy stored in plants and animals is used to perform mechanical work, such as moving around, growing, and reproducing.

Heat energy: The energy stored in plants and animals is eventually converted into heat energy through metabolism, respiration, and other processes.

Cow manure: Cow manure can be used as a biofuel inside the farmhouse. The cow manure is first converted into methane through the anaerobic digestion process. This methane can then be used to generate electricity through a generator. The heat produced during the generation of electricity can be used to heat the house. The remaining slurry from the anaerobic digestion process can be used as a fertilizer.

In summary, the energy flows from the sun to plants, then to animals, and eventually to heat energy, in the farm ecosystem. Additionally, cow manure can be converted into biofuel and used to generate electricity and heat energy inside the farmhouse.

suppose extracellular [k ] increases by 2.5 mm. if the original extracellular [k ] was 5 mm, how large (and in what direction) is the change in ek ?

Answers

The change in ek is +1.5 mV and it is in positive direction.

The Nernst equation is used to calculate the equilibrium potential (eK) of a given ion:

eK = (RT/zF)ln([K+]o/[K+]i)

Where R is the gas constant, T is the absolute temperature, z is the charge of the ion, F is Faraday's constant, [K+]o is the extracellular concentration of K+, and [K+]i is the intracellular concentration of K+.

In this case, we are given that the extracellular concentration of K+ increases by 2.5 mm. If the original extracellular concentration of K+ was 5 mm, the new extracellular concentration of K+ is 7.5 mm. We can plug these values into the Nernst equation to calculate the change in eK:

eK = (RT/zF)ln([K+]o/[K+]i)

eK = (RT/zF)ln(7.5/5)

eK = (RT/zF)ln(1.5)

eK = (RT/zF) × 0.405

eK = (RT/zF) × 0.405

eK = (8.314 × 300/1 × 9.648 × 104) × 0.405

eK = 1.5 mV
